You can have Array of dictionaries where each section will be represented by dictionary object. The key for the dictionary would be the section Title and the value would be an array of rows in section.

You can use NSPredicate to search the returned array from server and construct the data source array. NSPredicate Programming Guide

var arrData = Array<Any>()
var fromFilter:Bool = false
var arrStrData = Array<String>()

Step - 1 : Create UItableView in Your Story Board. - Datasource, Delegate

Step - 2 : import - UITableViewDelegate,UITableViewDataSource

Step - 3 : Implement methods

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
    return self.arr.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
    let cell = tableView.dequeueReusableCell(withIdentifier: "MainCell") as! MainCell
    cell.selectionStyle = .none

    var dictData: [String: AnyObject] = [String: AnyObject]()
    dictData = self.arrData[indexPath.row] as! [String : AnyObject]
    cell.lblName.text = dictData["name"] as? String ?? ""
    cell.lblEmail.text = dictData["email"] as? String ?? ""
    cell.lblAddress.text = dictData["address"] as? String ?? ""

    let image = dictData[""] as? String ?? ""
    cell.img?.sd_setImage(with: URL(string: image), placeholderImage: UIImage(named: "download.jpeg"), options: [.continueInBackground,.lowPriority], completed: {(image,error,cacheType,url) in

        if error == nil
        {
            cell.img?.image = image
        }
        else
        {
            cell.img?.image =  UIImage(named: "download.jpeg")
        }
    })
    return cell
}

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
{

}

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return 100
}
